V2I and V2V service demonstration of millimeter wave communication in urban road environment.

The demonstration result of a millimeter wave based communication system was introduced. The test system was set up in a complex urban road to demonstrate the service in vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) connection. Passengers in a vehicle can measure data rate using a commercial Apps and experience high-end data service by wearing augmented reality (AR) glasses. V2I had a maximum data rate of over 700 Mbps and V2V had a maximum data rate of over 800 Mbps. Passengers can experience stable AR service. However, the quality of service (QoS) was suddenly degraded due to the condition of wireless link. So, networks with more beam management capability should be considered in urban roads to avoid degradation of QoS.
